Naval has a simple test for spotting the person on your team who’s quietly holding everyone else back. You don’t run it on a spreadsheet or in a performance review, you run it in your own gut. Here it is in his own words.
The passage
First the setup, why this matters at all:
The best people truly only want to work with the best people. Working with anyone who’s not at their level is a cognitive load upon them. And the more people they’re surrounded by who are not as good as they are, the more keenly they’re aware that they belong somewhere else or they should be doing their own thing… The best teams are mutually motivated. They reinforce each other. Everyone’s trying to impress each other.
Then the test itself:
One good test is when you’re recruiting a new person, you should be able to say to them, “Walk into that room where the rest of the team is sitting, take anyone you want, pick them at random, pull them aside for 30 minutes, and interview them. And if you aren’t impressed by them, don’t join.” When you do that test, you will instinctively flinch at the idea of them interviewing randomly a certain person that’s kind of in the back of your mind. That’s the person you need to let go because that’s the person keeping you from having this high functioning team that all wants to impress each other. That’s the bar you have to keep.
What it actually means
The premise: great people are a flight risk around mediocre people. Not because they’re arrogant, but because working alongside someone weaker is a cognitive load. Every interaction quietly signals “I don’t belong here, I should be somewhere better or on my own.” So a team’s ceiling isn’t set by its best member. It’s dragged down by its weakest, because the weakest one is what makes your stars want to leave.
The test is a thought experiment, not something you literally do. You imagine handing a top recruit a blank check: pick anyone on the team at random, interrogate them for 30 minutes, and if you’re not impressed, don’t take the job. You’re betting the strength of your whole team on a random draw.
The trick is the flinch. When you run that scenario in your head, your gut reflexively tenses at one or two specific names, “god, I hope they don’t pick that person.” That involuntary reaction is the signal. You already know, below the level of arguing yourself out of it, who can’t clear the bar. The test isn’t generating new information, it’s surfacing a judgment you’ve been suppressing, because firing is uncomfortable and you’ve been rationalizing keeping them.
The conclusion is deliberately harsh: the person you flinch about is the person to let go. In Naval’s logic, that single weak link is “keeping you from having this high-functioning team that all wants to impress each other.” One mediocre hire doesn’t just do mediocre work. They lower the whole room’s standard and give your best people a reason to disengage.
Why it’s a sharp idea
- It converts a vague feeling into a decision rule. Everyone has a quiet “I’m not sure about so-and-so” instinct. Most managers bury it. This forces it to the surface and makes it actionable.
- It uses your best people as the measuring stick, not your own comfort. The bar is “would an A-player be impressed,” not “are they getting their tasks done.”
- It reframes failing-to-fire as an active cost. In the same conversation Naval puts it bluntly: “If you’re not firing, it means that you’re diluting yourself.” Keeping the flinch-person isn’t neutral, it’s actively diluting the team.
The honest caveats
Before applying it literally, three things worth keeping in mind:
- It’s calibrated for the early team, the first 10 to 40 people a founder directly manages. Naval says exactly that. It’s not a blanket rule for a 500-person org with many roles, tenures, and functions.
- A flinch can be wrong or biased. You might wince at someone for personality, communication style, or because they’re strong but unpolished, not because they’re actually weak. The flinch tells you where to look hard, not who to auto-fire. Treat it as a flag, not a verdict.
- It pairs with the rest of his hiring bar. After Buffett’s intelligence, energy, and integrity, Naval adds low ego, because you can manage 30 to 40 low-ego people but only about 5 high-ego ones.
Bottom line: it’s a forcing function for a decision you’re avoiding. If picturing your best employee randomly interviewing a teammate makes you wince, that wince is the data. Go figure out whether that person belongs, and most of the time you already know they don’t.
